CAR-COUPLING.

ESPECIPICATION forming part of Letters Patent No. 343,722, dated June15,1886.

Appllcation filed April 24, 1886. Serial No. 200,019.

To (ZZZ whom, it may concern:

Be it known that I, JACOB G. MOWRY, a citizen of the United States,residing at Rising Sun, in the county of Wood and State of Ohio, haveinvented a new and useful Improvement in Car-Couplings, of which thefollowing is a specification.

My invention relates to an improved carcoupling; and it consists of thenovel construction and arrangement and peculiar combination of parts,substantially as hereinafter fully set forth, and particularly pointedout in the claim.

In the accompanying drawings, Figure 1 is a perspective view of acar-coupling embodying my invention. Fig. 2 is a vertical centralsectional view through the device. Fig. 3 is a bottom plan view of myinvention. Referring to the drawings, in which like letters of referencedenote corresponding parts in all the figures, A designates thedraw-head, which is secured to the car-body in the ordinary well-knownmanner, and provided with the link-chamber A, which is of the ordinaryclass. The draw-headis provided with a longitudinal slot, B, that opensinto the chamber A and terminates a short distance from the frontthereof, to provide a solid front or cap, 0, to the draw-head; and thedraw-head is further provided near its rear end with integral abuttingflanges c, that bear against the car-body, and in the lower wall of itschamber with a short longitudinal slot, 0.

D designates a coupling bar or hook, which is arranged in the slot B,and is free to move longitudinally therein for a limited distance. Theupper edges of the draw-bar lie flush with or little below the upperedges of the slot in the draw-head, and at its front edge it is providedwith a depending hook, d, which is preferably curved or inclined, so asto permit a coupling-link of an approaching draw-head to enter. The rearend of the draw-bar or hook has aitransverselyarranged longitudinalslot, d, through which passes a pivot or bolt, d", that is also passedthrough and detachably secured in the draw-head, and the draw-bar iselevated by an oscillating arm or lug, D, that is journaled on a pin, Dand depends from and projects through the slot 0 of the draw-head, so asto be acted on by the devices for elevat- (No model.)

7 ing the hook-shaped end of the drawebar to release the coupling-link.The free hook-shaped end of the draw-bar is normally depressed andarranged in the path of an approach ing coupling-link by means ofaspring, E, one

end of which bears on the coupling-bar, and

journaled in suitable bearings, ff, and carries an arm or leg,f ,at itsinner end,that is adapted to impinge against the arm D, that elevatesthe draw-bar when the rock-shaft is turned by manipulating the handle orcrank f at the outer end thereof, the journal or bearing f being securedto the draw-head to support the inner end of the shaft, and the bearingfsecured to and depending from the car-body at the outer side thereof tosupport the outer end of the shaft.

G designates a vertical rod which extends to the top or roof of thecar-body to operate or elevate the free hook-shaped end of the drawbarfrom the roof, and this rod is journaled in suitable bearingsg g,securedto the draw-head and car-body. The upper end of the rod is provided witha handle or band-wheel, h, to be grasped and turned by hand, and thelower end of the rod is provided with a right-angled crank, I, that haspivoted to its free end alink,

'L', which in turn'is pivoted to the free end of the arm D, to elevatethe draw-bar.

This being the construction of my invention, the operation thereof is asfollows: When the coupling-link of an approaching car enters thedraw-head and strikes the inclined or curved edge of the draw-bar hookat, the latter is elevated against the tension of the pressurespring andis forced rearwardly'for a limited distance, thus permitting the link topass beneath the hook and engage the hook d, thus automatically couplingthe cars. Theimpact ofthe couplinglink on the draw-bar forces itrearward ly, as above mentioned, to reduce the shock on the parts of thedraw-head, and when the cars are started or in motion the link draws thecoupling-bar forward, and the front end thereof engages with the cap 0,thus providing an increased bearing-surface therefor. To nncouple thecars, the rock-shaft or vertical rod G is operated by hand from the sideor roof of the car-body to elevate the upper end of the oscillating armD; and consequently the hookshaped end of the coupling-bar, whereby thehook d is drawn from engagement with the link, and the latter can thenbe easily Withdrawn from the drawhead. It will thus be seen that Iprovide an improved coupling which will automatically couple the carsand can be operated to uncouple the cars from either the side or roof ofthe same, thus providing means which does not require the brake man toendanger his life in passing between the ears to couple or uncouplethem. The rod G has a projecting pin, j, that bears against thedraw-head to limit the rotation thereof.

In lieu of supporting one end of the spring on a pin or boltand havingits opposite end bear on the draw-bar, the spring can be rigidly securedto and carried by the coupling-bar and bear on the draw-head or otherdevice at its opposite end to normally depress the hookshaped end of thedraw-bar in the path of an approaching link.

Having thus fully described my invention. what I claim as new, anddesire to secure by Letters Patent, is

As an improvement in car-couplings, a drawhead having the longitudinalslotsinits upper and lower walls and a solid cap, 0, at thei'rontthereof, in combination with a slotted coupling-hook pivoted in thedrawhead and capable of a limited longitudinal movement therein, aspring, E, for normally depressing the hook-shaped end of thecoupling-hook in the path of an approaching link, a swinging rockingarm, D, journaled in the slot 0 of the draw-head and bearing against thecouplinghook in front of thepivot thereof, a horizontal rock-shaft, F,having an arnnf, at its inner end for acting on the arm D, a verticalrod, G, carrying a right angled arm, I, at its lower end, and aprojecting pimj, that is adapted to abut against the draw-head and limitthe rotation of the said rod Gin one direction,and a link intermediateof the arms I and D, all arranged and combined substantia ly asdescribed.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in presence of two witnesses.

JACOB O. MOWBY.
